Find the Reference Angle 600
Problem
Solution
Subtract multiples of
360^∘ to find the coterminal angle within the range[0^∘,360^∘)
Identify the quadrant where the angle
240^∘ terminates. Since180^∘<240^∘<270^∘ the angle is in Quadrant III.Apply the reference angle formula for Quadrant III, which is
θ^′=θ−180^∘
Calculate the final value.
